Festival Companion App

A Flutter app with the programme, reminders, a stand map and push alerts for a multi-day festival

A multi-day festival needed one app for visitors and vendors. Our team developed it in Flutter and Dart with BLoC, for Android and iOS: a programme with reminders, a Google Maps stand map, push alerts and vendor tools.

The product

What it does, and for whom

A festival runs across several days and many locations, so people need to know what is on, when, and where to find it. The app keeps the programme by day, lets people set reminders and add events to their calendar, and shows stands and facilities on a map. Tickets and cashless payments open inside the app as a third party's web pages.

Scope: Ticketing and cashless are a third party's web pages shown inside the app, and there is no native QR ticketing. The back end and admin panel are not part of what we are describing here. Our work was the mobile app.

The product in use

Inside the app

  1. The programme by day

    Each festival day has its own list of events with time and location, and each event can have a reminder.

    Recreated Programme screen for Day 1, with an enlarged list of example events from Stands open at 17:30 to First day closes at 23:00, each with a location and a bell, three of them highlighted as reminders
    Day 1 of the programme. Close-ups on phones: tap any image for the full screen.

  2. Reminders, calendar and push alerts

    An event's page sets a reminder or adds it to the phone's calendar. Push alerts are sent through Firebase Cloud Messaging.

    Two recreated screens: a Street parade event with a Reminder switch turned on, Add to calendar and Show on map; and the home screen with quick access to programme, stand map, tickets and cashless, vendor tools and three example alerts
    An event page and the home screen. Close-ups on phones: tap any image for the full screen.

  3. A stand map on Google Maps

    Stands and facilities appear on the map, and people can get directions to a stand.

    Recreated map screen with numbered groups of stands and a legend on a drawn map, beside an enlarged card for Stand 24, a food stand at Market Square, with a Directions button
    Stands, facilities and directions. Close-ups on phones: tap any image for the full screen.

About these images: the screens are recreated for this case study, with its own colours, neutral naming and an example programme in place of the client's brand and content. The map is a drawing. The layouts are illustrative and none of them are screenshots of the app.
